CTUATING MECHANIVSIVI iFOR AWNINGS.

SPECIFICATION forming part of Letters Patent No. 648,478, dated May 1, 1,900, Application filed July 6, 1,899. Serial No. 722,935. (No model.)

To all whom/it may concern:

Be it known that LWILLIAM H. ARNOLD, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Actuating Mechanism for Awnings; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and vuse the same, reference being had to the ac-l companying drawings, and to the tigures of reference marked thereon, which form a part of this speciiication.

My invention relates more particularly to that class of mechanics adapted for use particularly in manipulating and regulating awnings, but may be used for many Aother purposes, including the transmission of motion from electric motors in cars to the tractionwheels thereof, the operation of hoisting Inachinery in mines, the operation of turrets and guns on war vessels, the operation of capstans on vessels, &c.

My object is to furnish a gear suitable forA raising and manipulating awnings, dac. ,which may be easily manipulated, effective in its operation, and durable and cheap in its construction. This I accomplish by the use of the peculiar construction, novel combination, and adaptation of parts hereinafter described, and particularly pointed out in the claim hereunto annexed, reference being had to the accompanying drawings for a better comprehension hereof, in which- Figure l is a front elevation of my invention having the front plate removed. Fig. 2 is a longitudinal section of the drivin g-gear. Fig. 3 is a cross-sectional view of the-driven gear. Fig. 4 is an elevation of the end of the driven shaft, showing the journals thereon.

Similar igures of reference'indicate corresponding parts in the several views.

My invention consists of two angular toothed or worm gears 1 and la, arranged with their axes at right angles to one another, the teeth 2 of said gears being arranged at an angle of fortydive degrees (45) with relation to the line of the axis, said teeth 2 being located at suitable intervals on the periphery of the body of said gears. The teeth 2 are arranged over the center longitudinally of ,casing 3 for that purpose.

the gears and the ends are tapered slightly.

The gears 1 and la are` located in a metallic casing 3 of the required shape and size, preferably square or in the general form of a parallelepiped and havin g lugs 4 rigidly attached to its base, wherewith it may be attached in position. Altace-plate (not shown) may be attached over the front of the casing for the purpose of keeping out dust and also to support the outer or front end of the gear l. The gear 1 is arranged horizontally in one end of the casing 3 and has its rear end 5 journaled in the rear wall of the casing, there being an Openin g therein for that purpose. The front end of the said gear l has a square opening 6 therein, which extends to near the center, as shown in Figs. l and 2.. `The front end-of the gear has a shoulder 7 formed thereon, against which the front plate (not shown) rests, thereby forming a journal and bearing.

A shaft 8 has a collar 9 rigidly attached to the same at a suitable point thereon, which said collar 9 is adapted to rest and rotate in an opening in the top sidevof the casing therefor. The lower or extreme end 13 of said shaft 8 is lround and adapted to be inserted in a smaller opening in the lower side of the The intermediate portion 11 between the end of the shaft S and the collar 9 is square and tapering toward the end and is adapted to fit closely into a square opening 10, which extends the entire length of the gear la. The collar 9 is adapted to engage with`the top end of the gear la, thereby ,preventing the same from passing too far through the said gear, which has a circular shoulder 12 on its lower end, which engages with the casing, as shown in Fig. l.

`My invention differs from the screw or worm gear as heretofore applied in that the teeth orl cogs 2 are constructed at the same angle On each wheel, which gives more facility in operation and combines durability, speed, and eiiiciency. i

The advantage of my invention is that its compactness renders it more desirable for lo- IOO y a The easing Ei'isv rigidly attached to the Wall vof a.l building in a jsnitable locality` Within easy reach of therground bythe klugs 4:., The

,gear la is lthen' inserted in position within the said easing 3 andthe shaft Sinserted from the` top `into the `seats inthe easing therefor and thronghfthej` open-ing 10 inthe geajrj'la i' aforesaid( As will-be seen, fthe opening l10 inthe gearland -theportion 1l of the'shaft 8 both bei-n g 'square motion is readily'imr'iarted from one-tothe other. The gear -1 is `thenplaced in position,iwi,th its rear end 5 seated in the rearwall ofthe easing 3 andv the teeth 2 offboth gears Vengaging with one another! The face-plate is thenplaeed in position over' l Y, the gearsand againstthe shoulder 7 of. the gear-1 and attached bysorews in therhjo1esl4-y A's'nitable erankforhjandle, maybe inserted :intothe sqnareopening k6 in the gearl, Wherelwith the' gears may be ,manipulatedfor-Wardlly or'rearwardly, as is desired. g v A I i lain well aware that wheels have beenoonv W strneted with teethk adapted to -engage with al V 1 shaft yhaving" a lsereW-thread formed-thereon ;v

but these are'not adapted for' speed orgconipaetness and I therefore do not claim such broadly; but 'I i V'What I do claim as new, and desire to seeure by Letters Patent, is;

In al1-actuating mechanism, the combination `of` the easing 3,1thej gear 1a having its teethtvat anl angle with its axis, inserted in one end of the casing 3, th'eshaft 8, provided "with the square portion 11 and: thecollar 9, `inserted thronghthe vgear la and'seated in.y ,-the casing 3,'the gear-f1 having angular teeth thereon inserted` in the easing 3 at right angles to thev gear lafan'd seated in the easing 3, 'st'xitable r'neans for closingA said easing and Suitable means for operating said gear 1, all arranged andopera-ti'ng substantially as shown andv described andv for the Vpurposesset forth.

in presence of two witnesses.
